Did You Know?

Stridulate is one member of a word family that has its ancestry in the Latin word stridulus, meaning "shrill." Also in this family is "stridulation," a noun that can either refer to the shrill sound made when an insect stridulates or can simply mean "the act of stridulating." Another "stridulus" word is stridulatory, meaning "able to stridulate" or "used in stridulation." There's also stridulous, meaning "making a shrill creaking sound." "Stridulus" itself comes from "stridere," which is the direct source of the last word we'll mention here. Stridor means "a harsh, shrill, or creaking noise" and also "a harsh vibrating sound heard during respiration in cases of obstruction of the air passages."
